Abstract

Exercise is recommended as a non-pharmacological, non-invasive intervention for osteoarthritis (OA) of the knee. Physiological data concerning the duration and intensity of muscle activity or physical activity profiles during normal daily activity for this population is lacking. Our aim was to explore this using surface Electromyography (EMG) and accelerometer-based activity monitoring. Thirty-four patients with knee OA, mean (SD) age 63.2 (9.8) years and 30 aged-matched asymptomatic controls 64.1 (10.9) years participated. The duration of recording was similar in knee OA and control groups – median (IRQ range) 12:34 (10:11–14:17) h and 13:10 (12:02–14:56) h, respectively (p = 0.514).
